TXT is a DNS record, which contains info in human-readable form for external sources to gain info about a specific domain name or subdomain. In the most common scenario, this sort of record is employed to prove that you own a domain name if you are trying to add it to a search engine or to some site traffic analytics platform. Since just the domain address owner/administrator may add custom DNS records, the TXT record serves as a verification of ownership for the business providing the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) security, which ensures that a particular email address shall not be spoofed and that individuals will not get junk e-mail from allegedly your mailbox. The TXT record features info about the mail server where your electronic messages come from and functions as proof that it is a reliable one. As there are no rules about the content of this type of a record, you can add any other info as well.
